How to measure SNR (Signal-to-Noise Ratio) of a Audio signal

Hello,
I have an audio signal that I received over radio. How do I measure the SNR using power spectral density ? I know I have to integrate to get the power, bu how do I know what is signal and what is noise by the PSD alone ?

Hi Pedro,
To measure the SNR of a signal, you can simply use the MATLAB function "snr(x)", where x is the input signal.
If you want to measure the SNR specifically using PSD, then you can do that by leveraging the "periodogram()" function. See SNR of Sinusoid Using PSD example for more information.
